A detector 28 capable of detecting the state is provided, and the related control of the paddy supply control valve 26 by the layer thickness detector 23 is stopped from the start of the operation of the husking section 1 to the time when the detector 28 is not detecting grains. A stop command signal and a control command signal for controlling the paddy supply regulating valve 2G in the layer thickness detector 23 in relation to the grain detection state of the detector 28 are output to the regulating means 29 of the paddy supply regulating valve 26. The present invention is directed to a structure of a paddy supply valve regulating device for a huller sorting machine characterized by having a control command means. It is equipped with a rotary sorting tube 11 which is configured with a large number of pot holes and rotates around a horizontal axis, and is configured to be able to supply the scraped rice after the dehulling wind sorting in the dehulling section 1 to the rotary sorting tube 11. , a return path is provided to return the grains sorted in the rotary sorting tube 11 to the shucking section 1, and a reduced grain detector 28 capable of detecting the reduced state of the grains is provided in this return path to remove the reduced grains. The grain detector 28 and the paddy supply control valve 26 of the husking section 1 are connected in a related manner, and from the start of the operation of the husking section 1 until the grain non-detection state of the reduced grain detector 28, the reduced grain is detected. A control stop command signal is issued to control the paddy supply control valve 26 in the container 28, and in the grain detection state of the reduced grain detector 28, paddy is supplied based on the detection result of the reduced grain detector 28. The structure of the paddy supply valve regulating device for a rice hulling sorter is characterized in that it has a control command means for outputting a control command signal for controlling the regulating valve 26 in relation to the regulating means 29 of the paddy supply regulating valve 26. That's true.

[Function and effect of the invention]

In the invention of Item 1 I-1, in a normal state where the sorting work is stable after a predetermined period of time has elapsed from the start of the hulling work, the rotary sorting cylinder 1
1 detects the amount of grains to be sorted with the layer thickness detector 23 in
6 to reduce the amount of grains to be sorted into the rotary sorting tube 11, and when the amount of grains to be sorted in the rotary sorting tube 11 is small, the amount of grains to be sorted in the rotary sorting tube 11 is reduced. This is because the amount of grain to be sorted in the rotary sorting tube 11 is optimized by increasing the supply amount of the paddy supply control valve 26 on the first side to control the increase in the amount of grain supplied to the rotary sorting tube 11. At the time of starting the hulling work in the hulling section 1, from the start of the work until the reduced state of the grains is detected by the reduced grain detector 28 in the grain returning path, that is, the grains to be sorted are placed in the rotating sorting cylinder 11. The automatic opening/closing control of the paddy supply control valve 26 of the hulling section 1 is stopped until the grains are supplied and the unhushed grains discharged from the sorting terminal side are returned to the hulling section 1. Since the opening degree of the paddy supply control valve 26 cannot be adjusted to increase beyond the predetermined opening degree, a larger amount of grains to be sorted than the normal amount of grains to be sorted is transferred to the rotating sorting tube at the start of hulling sorting. By preventing grains from being supplied to the rotary sorting tube 11, the amount of grains to be sorted is optimized from the start of the sorting operation to the rotary sorting tube 11, and the sorting accuracy in the rotary sorting tube 1] is improved. It is something that can be done.

In the second aspect of the invention, in a normal state where the sorting work is stabilized after a predetermined period of time has elapsed from the start of the hulling work, the opening/closing degree of the paddy supply control valve 26 of the hulling section 1 is adjusted to When the amount of grains discharged from the terminal end and returned to the husking section 1 is large, the amount of grain supplied by the paddy supply control valve 26 on the husking section 1 side is reduced to reduce the amount of grain to be sorted to the rotary sorting tube 11. The amount of grain supplied is controlled to decrease, and when the amount of grains discharged from the sorting end side of the rotary sorting tube 11 and returned to the husking section 1 is small, the paddy supply control valve on the husking section 1 side is controlled. 26 to increase the amount of grains to be sorted to be fed to the rotary sorting cylinder 11,
Since the purpose is to optimize the amount of grains to be sorted in the rotary sorting tube 11, when the hulling operation in the hulling section 1 starts, the reduced state of the grains is checked in the grain return path from the start of the operation. Until the kernels are detected by the grain detector 28, that is, until the grains to be sorted are supplied into the rotary sorting cylinder 11 and are discharged from the sorting terminal side, the husking section 1 is in a normal sorting state. Paddy supply control valve 2
6 has been discontinued, and the opening degree of the paddy supply control valve 26 cannot be adjusted to increase beyond the predetermined opening degree. By preventing the amount of grains from being supplied to the rotary sorting tube 11, the amount of grains to be sorted is optimized from the start of sorting work to the rotary sorting tube 11, and the sorting accuracy in the rotary sorting tube 11 is improved. 1- can be achieved.

When carrying out hulling work, raw rice is supplied to the rice hopper 2, and each rotating part of the hulling and sorting machine is driven. Then, the paddy supplied from the paddy hopper 2 to the husking section 1 is subjected to the husking action, the husked rice is wind-selected in the husked rice winding path 4 below, and the rice husks are discharged from the dust exhaust pipe 6 to the outside of the machine. be discharged. The mixed rice of brown rice and paddy is dropped into the sliding rice receiving trough 7, fried by the mixed rice lifting machine 8, passed through the mixed rice hopper 9, and sent to the starting end of the supply 4i11i14 on the rotary sorting cylinder 11 side. It is further supplied to the supply side end of the km tube 11 by the supply helix 13 in the supply@X14.

Next, the mixed rice is pumped through the pot hole of the rotary sorting tube 11 rotating clockwise in Fig. 2]--Gried, and brown rice with short grain length is pumped high and processed.--Rice@16 fell into
Paddy grains with long grain length and some brown rice are pumped up low and fall into the supply gutter 14 where they are sorted. The unsorted mixed rice that has fallen into the feeder [14] is fed again into the rotary sorting cylinder 11 from the conveyance end of the feeder @14 by the feeder helix 13, and is re-sorted.

In addition, the finished rice that has fallen into the finishing rice gutter 16 is conveyed to the finishing rice helix 15 to the rice flow lower tube 17, passes through the finishing rice grain plate 18, and falls to the finishing rice receiving gutter 19. The grains are sorted by a sorting wind and taken out of the machine by a finishing rice grain board 20.

The grains, mainly consisting of paddy, sent to the discharge end of the rotary sorting tube 11 after sorting flow down to the lower paddy tray @21, are fried by the paddy lifting machine 22, and sent to the threshing section 1. It is reduced and subjected to the de-pudding action again in the arm part 1.

As described above, the hulling sorting work is performed, but in a normal sorting state where the grains to be sorted are distributed from the sorting start end side to the sorting end side of the five-rotation sorting tube 11, the rotation sorting tube 11 The layer thickness detector 23 detects the amount of grains to be sorted in the paddy layer, and a control command signal from the CPU 32 is output to the paddy supply control motor 29 in accordance with the increase or decrease in the amount of grains to be sorted. 1
The opening degree of the paddy supply control valve 26 on the side is adjusted to the closed side or the open side, and the amount of grains to be sorted to be supplied to the rotary sorting tube 11 is controlled to the decreasing side or increasing side.

When the grains are discharged and the grains to be sorted are distributed over the entire area of the rotary sorting tube 11, automatic control is started based on the detection results of the next brown rice detector 34 and the reduced grain detector 28. . That is, a. The detection information of the brown rice detector 34 and the reduced grain detector 28 is compared with the set standard information, and if the ratio of reduced grain amount is higher than the ratio of brown rice, a reverse drive signal is sent from the CPU 32. It is sent to the paddy supply control motor 29 via the output interface 33 and the relay 36, and controls the paddy supply control valve 26 to the reduction side. It is compared with the setting standard information,

In step 8, the amount of brown rice and the amount of reduced grains are detected, and this detected information is compared with the reference information.
The control command signal from CPtJ32 is sent to the paddy supply control motor 2.
9, and the opening degree of the paddy supply control valve 26 on the side of the husking section 1 is
Adjusting to the closed side or the open side to control the supply amount of grains to be sorted to the one-rotation sorting tube 11 to the decreasing side or increasing side,
Hulling and sorting work is carried out while the amount of grains to be sorted in the rotary sorting tube 11 is maintained appropriately.

When the start switch (not shown) is turned on to start the hulling and sorting work, from the start of the work until the reduced grain detector 28 starts detecting the reduced grains, in other words, the removed rice in the hulling section 1 is Until the grains are supplied to the rotary sorting cylinder 11, sorted and discharged from the sorting end side, and the grains to be sorted are distributed over the entire area of the rotary sorting cylinder 11, the paddy supply control valve 26 is kept at a small opening. The command signal to be set is sent from the CPU 32 to the relay 35.
The paddy supply control valve 26 supplies paddy to the hulling section 1 with a small opening degree, and a small amount of grain to be sorted is supplied to the rotary sorting cylinder 11. This prevents a large amount of grains to be sorted from being supplied to the rotary sorting tube 11 at the start of work, and improves sorting accuracy.

In addition, in conjunction with the start of detection of the reduced grain detector 28, the reduced grains returned from the sorting end side of the rotary sorting cylinder 11 to the shucking section 1 are switched to automatic control of the paddy supply control valve 26. Therefore, depending on the moisture content or variety, the rotary sorting cylinder 11
